Optronic fuse device for a flying object

Abstract

Described is an optronic fuse device ( 10 ) for a flying object such as a drone, a rocket or an aircraft, comprising a sensor window ( 14 ) which is provided for its optical arrangement ( 12 ) and with which is associated an air deflection device ( 16 ) in order to keep the air flow of the flying object in flight away from the sensor window ( 14 ) and to deflect it past the sensor window ( 14 ) and in that way to prevent fouling and/or icing of the sensor window during the mission of the flying object.

1 . An optronic fuse device for a flying object such as a drone, a rocket or an aircraft, comprising a sensor window ( 14 ) provided for its optical arrangement ( 12 ), characterised in that associated with the sensor window ( 14 ) is an air deflection device ( 16 ) which deflects the air flow ( 18 ) of the flying object in flight past the sensor window ( 14 ).  
     
     
         2 . An optronic fuse device according to  claim 1  characterised in that the air deflection device ( 16 ) is in the form of a spoiler nose ( 20 ) which produces a transverse air flow.  
     
     
         3 . An optronic fuse device according to  claim 2  characterised in that the spoiler nose ( 20 ) is disposed radially displaced with respect to the sensor window ( 14 ).  
     
     
         4 . An optronic fuse device according to  claim 2  or  claim 3  characterised in that the spoiler nose has a forwardly obliquely inclinedly extending side edge contour ( 22 ).  
     
     
         5 . An optronic fuse device according to  claim 4  characterised in that the spoiler nose has a cylindrically concave afflux surface.  
     
     
         6 . An optronic fuse device according to  claim 5  characterised in that the cylindrically concave afflux surface of the spoiler nose is of a concavely recessed configuration in the form of a surface of a sphere.  
     
     
         7 . An optronic fuse device according to one of  claims 4  to  6  characterised in that the side edge contour ( 22 ) of the spoiler nose is of a stepped configuration.
